public sealed class DisposeSentinel

Remarks

The methods in 
DisposeSentinel
are used by NativeContainer instances to automatically track memory leaks, and report them to you. However, you should use the UnsafeUtility.MallocTracked method over 
DisposeSentinel
where possible.
DisposeSentinel
is a managed object that's only referenced by the 
NativeContainer
that holds the native data that you don't want to leak. The 
DisposeSentinel
finalizer is invoked when there aren't any references to the NativeContainer that owns it, and checks if the referenced data has been disposed correctly. If the data hasn't been disposed of correctly, 
DisposeSentinel
logs an error containing the information about when the initial allocation happened.
DisposeSentinel
creates garbage for the garbage collector to pick up, and any memory leaks are reported upon domain shutdown or reload.
You can only use the 
DisposeSentinel
class when ENABLE_UNITY_COLLECTIONS_CHECKS is defined.
